Description

Technical Field

[0001] The invention relates to the field of building electromechanical construction technology, and in particular to a construction method combining permanent and temporary combined with voltage-reducing lighting at a construction site. Background Art

[0002] When installing and arranging the pedestrian lighting at the construction site in the basement of the garage: according to the specifications, safe voltage needs to be used. The traditional lighting installation method is generally to install a separate pedestrian light transformer, reduce the 220V voltage to 36V safe voltage, and then power the LED light strip for lighting. However, using this method, a pedestrian light transformer is also required to meet the low-voltage lighting requirements of the garage. This traditional construction method is not only inefficient, but also needs to be dismantled after the construction is completed. The resource utilization rate is not high and it does not meet the requirements of resource-saving projects. Summary of the invention

[0003] The present invention aims to solve the above problems, thereby providing a construction method combining permanent and temporary lighting with step-down lighting at a construction site.

[0004] The present invention solves the above-mentioned problem by adopting the following technical solution: A construction method for permanent and step-down lighting at a construction site is carried out in the following steps: Step 1: Insert the BV wire to be used later into the lighting wire tube reserved on the top plate, and install the lighting lamp holder in the pre-buried wire box, and connect the lighting lamp holder to the BV wire; Step 2: Install the temporary lighting fixture on the lighting fixture holder in the pre-buried wire box; Step three: add a temporary lighting distribution box on one side of the temporary primary distribution cabinet arranged at the construction site. A step-down module is installed in the temporary lighting distribution box. The input end of the step-down module is electrically connected to the temporary primary distribution cabinet, and the output end of the step-down module is connected to the BV line.

[0005] The step-down module is a 220V to 36V power supply module.

[0006] Compared with the prior art, the present invention adopting the above technical solution has the following outstanding features: The method described in the present invention is to insert the BV line to be formally used later into the lighting line tube reserved in the top plate, and then install the lighting fixtures. When the BV line is formally used later, it does not need to be removed, and only the temporary lighting fixtures need to be removed. Compared with the previous temporary lighting methods, the construction progress of the later installation is accelerated, and the construction cost is saved. All BV lines are passed through the lighting line tube pre-buried in the wall panel, without exposed wires, to prevent danger, which is safer and more reliable. By adding a temporary lighting distribution box and setting a step-down module, the previous steps of installing a running light transformer and wiring the temporary lighting are omitted, which accelerates the construction progress and reduces the construction wiring cost of temporary electric lighting. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0008] The present invention is further described below in conjunction with embodiments, the purpose of which is only to better understand the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.

[0009] See also Figure 1 , a construction method of permanent combined with step-down lighting at the construction site, is carried out according to the following steps: Step 1: Insert the BV line 4 to be used later into the lighting line tube 5 reserved on the top plate, and install the lighting lamp holder in the embedded wire box 6, and connect the lighting lamp holder to the BV line 4.

[0010] Step 2: Install the temporary lighting fixture 7 on the lighting lamp holder in the pre-buried wire box 6.

[0011] Step three: Add a temporary lighting distribution box 2 on one side of the temporary primary distribution cabinet 1 arranged at the construction site. A step-down module 3 is arranged in the temporary lighting distribution box 2. The input end of the step-down module 3 is electrically connected to the temporary primary distribution cabinet 1, and the output end of the step-down module 3 is connected to the BV line 4.

[0012] The step-down module 3 is a 220V to 36V power supply module; it converts the temporary 220V electricity into a safe voltage of 36V to meet the requirements of low-voltage lighting in the garage.

[0013] The method described in the present invention is to insert the BV line to be formally used later into the lighting line tube reserved in the top plate, and then install the lighting fixtures. When the BV line is formally used later, it does not need to be removed, and only the temporary lighting fixtures need to be removed. Compared with the previous temporary lighting methods, the construction progress of the later installation is accelerated, and the construction cost is saved. All BV lines are passed through the lighting line tube pre-buried in the wall panel, without exposed wires, to prevent danger, which is safer and more reliable. By adding a temporary lighting distribution box and setting a step-down module, the previous steps of installing a running light transformer and wiring the temporary lighting are omitted, which accelerates the construction progress and reduces the construction wiring cost of temporary electric lighting.
